The Lowdown
Alright, this is Rusty comin' at ya from the desk. Let's get into it.
Alright, the next couple of weeks here at Jaconé are a bit of a mixed bag, but there's a couple of windows that are gonna be worth paddling out for. We've got some small, clean days early on and then a couple of heavy hitters further out if you've got the skills.
The first real window of opportunity kicks off Saturday morning, the 1st of August. We've got a clean 4 ft S swell rolling in with a 12-second period, and the wind is offshore from the NE at 9 mph. That's a good combo for a fun session. The water temp is sitting around 72°, which is pretty much bang on average for this time of year, so no complaints there.
The real standout, though, is looking like Friday, the 14th of August. The morning session is looking unreal. We're talking a 4 ft S groundswell with a very long 15-second period. The energy is solid, and it's glassy - zero wind. That's a recipe for some clean, powerful lines coming through. A long period swell like this is gonna have some real push to it, so it'll be best if you can find a nice peak. It's not for the faint of heart, but it's the best on offer.
Now, if you're an experienced surfer, keep your eyes on Saturday, the 15th of August. The morning is gonna see a massive 10 ft SSW swell with a 12-second period. The energy is off the charts. But look, that's a whole lot of water. The forecast is saying it's simply too big for this break, so only the heaviest of chargers are gonna be able to handle it. The wind is light and cross, so it might be clean, but it's a dangerous beast.
The rest of the period is a bit of a waiting game. We've got a few mornings with glassy conditions and small 2 ft swells, but they're mostly short-period windswell. The wind is good, so you can get a log out for a cruise, but don't expect anything with real power. There's a stretch from the 9th through the 12th where the swell drops right off, and the wind gets messy, so it'll be a quiet few days.
So, to sum it up: get out there Saturday morning, the 1st, for the first fun one. The big one to circle on the calendar is Friday morning, the 14th, for some proper glassy groundswell. And if you're a real chargers, look at the 15th, but be very careful.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
